what town are you playing? If by chance your in Twinbrook, try looking over on the other side of the rail road tracks in frount of the scince bulding. Sunset I don't know, Riverview I dont know that one either maybe someone else can help you with them.
If you are on the opportunity where you need palladium and there aren't any map tags, then there isn't any palladium to find. You'll have to wait for some to spawn. Check the map at least once a day.
I found my pallaium around the garden in the outstanding citizens corps by drilling it takes a long time to find it, at least for me it did but the drill still does the job.
